Chemical Structure

4-Methoxycyclohexene-1-boronic Acid Pinacol Ester CAS 1092938-92-5 chemical structure

Description

4-Methoxycyclohexene-1-boronic Acid Pinacol Ester (C13H23BO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

CATO supplies 4-Methoxycyclohexene-1-boronic Acid Pinacol Ester (CAS 1092938-92-5), a certified reference material (molecular formula C13H23BO3, MW 238.13 g/mol) for analytical method development and quality control.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
